Abstract: The invention relates to a film for surface protection having at least one base layer and a surface layer for removably adhering to a substrate comprising at least 40 wt % of an elastomeric propylene-based polymer with a heat of fusion derived from isotactic propylene type crystallinity as determined by DSC of less than 40 J/g and optionally an ethylene-based polymer in the form of an ethylene-alpha-olefin copolymer having a density of less than 0.91 g/cm3 and/or an ethylene-vinyl ester copolymer having from 5 to 60 wt % of the ester derived units and/or optionally less than 40 wt % of a propylene based polymer having a heat of fusion of greater than 70 J/g. The films have good initial tack.

Abstract: Resins and oligomer materials and/or combinations thereof grafted with an unsaturated acid or anhydride, such as maleic anhydride, are disclosed herein. The grafted materials are useful in adhesive formulations, particularly in hot melt adhesive applications.

Abstract: This invention relates to novel resins, blends of the novel resins with base polymers and a process for producing a resin comprising combining a reactor feed blend comprising: (a) at least 2 weight % of isoprene, (b) at least 2 weight % of one or more of dicyclopentadiene, substituted cyclopentadienes and substituted dicyclopentadienes, (c) at least 2 weight % piperylene, (d) at least 1 weight % aromatic olefins, and (e) 0 to 92 weight % of additional aliphatic olefins, based upon the weight of the reactor feed blend, with a polymerization catalyst under polymerization conditions, preferably where the ratio of component (c) to component (b) is less than 8 and the ratio of component (a) to component (b) is less than 5.

Abstract: This invention relates to an improved resin hydrotreating process which maintains resin softening point and aromaticity as well as catalyst lifetime. The process is particularly useful for hydrotreating resins containing one or more halogen residues. Pressures are maintained at 2000 psi or less. Color is substantially reduced while softening point is not decreased by more than 8° C.

Abstract: This invention relates to an adhesive composition comprising a copolymer comprising units derived from one or more macromonomers and an unsaturated acid or an unsaturated anhydride wherein the weight average molecular weight of the copolymer is at least twice the weight average molecular weight of the macromonomer, the melt index of the copolymer is 1 dg/min or more, and wherein the macromonomer:(1) has a weight average molecular weight between 500 and 100,000;(2) has at least 30% terminal unsaturation; and(3) comprises a copolymer of ethylene and at least one .alpha.-olefin, and/or a copolymer of propylene and ethylene or an .alpha.-olefin.
